Trump knocked her once at the time of the incident; however, I think he immediately saw the error of his assumptions about Geller, and has never knocked her since, not even once. He should have gotten more information about her first. but Trump shoots from the hip, and occasionally draws too fast, lol. But that’s Trump, and it is also what makes him endearing, as well as occasionally exasperating.
He should have already had enough information about the 1st Amendment.
